305-046-521-507

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-507 is a standard card edge connector from the 305 series, designed for panel mount vertical installation. It features 46 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector accepts non-specified double-sided card edges and utilizes gold-plated copper alloy contacts with a thickness of 10.0 µin (0.25 µm). Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C. The housing is made of green thermoplastic polyester, and the unit includes flush mount flanges with top openings and M3 threaded inserts.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and row configuration before ordering. Confirm that the mating card edge thickness falls within the specified operational range to ensure proper contact engagement. Check for RoHS3 compliance requirements if environmental regulations apply to your assembly. Ensure that the M3 threaded insert specifications align with your panel mounting hardware constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for panel mounting applications. Consider the 5 A current rating and operating temperature range to ensure suitability for the intended electrical environment. Verify that the gold plating thickness meets the durability needs of the expected mating cycles. Compare against other 305 series variants if different position counts or flange features are needed.
